Start a Contracting Business in Washington, DC

Knowing your trade is one thing. Starting the business that delivers it is another. In Washington, DC, that difference matters particularly because registering a company, obtaining a Basic Business License (BBL), securing trade qualifications, and securing a building permit are separate steps.

This is a guide to getting oriented and running a contracting business responsibly in the District. It is not a one-license-fits-all recipe: your work type and location determine which requirements apply. If a source leaves a question unanswered, we link to the appropriate agency rather than guess.

1. Your quick-start checklist

Before you advertise or accept a paid project, work through these questions:

What specific services will you perform, and which DC business-license category fits them?
Is your entity registered and in good standing where required?
Have you completed tax registration and the Clean Hands requirement?
Does your business location require a Certificate of Occupancy or Home Occupation Permit?
Have you obtained the right DC Basic Business License and any individual trade credentials?
Do you need the home improvement surety bond, a designated licensed salesperson, or specific customer-contract forms?
Have you checked building permits and set up sensible estimating and project records?

The District’s official BBL steps provide the general sequence.

2. Choose your work—and your licensing category

Start with a focused service: remodeling, roofing, maintenance, painting, or another trade you can competently and legally perform. But do not assume every contractor uses the same DC license.

The Department of Licensing and Consumer Protection (DLCP) lists General Contractor/Construction Manager and Home Improvement Contractor as distinct Contractor and Construction Services business activities. The official page describes General Contractor A, B, C, G and H categories, but these should not be confused with Virginia’s Class A, B and C licensing thresholds. Check directly with DLCP about the category for your scope.

Certain regulated trades—such as electrical, plumbing/gasfitting, or refrigeration/air conditioning—may require additional licensing under the Board of Industrial Trades.

3. Register your business and tax accounts

Choose the business structure that suits your ownership, risk and tax situation. An LLC is common, but it is not the only legal option and it does not automatically grant a contracting license.

DLCP’s BBL sequence calls for corporate registration when applicable, a registered trade name if you use one, federal identification, DC tax registration, and Clean Hands compliance. A business operating from a commercial District address may need a Certificate of Occupancy; a District home office may require a Home Occupation Permit.

Use the official four-step licensing guide, and verify your particular situation before filing.

4. Apply for the right Basic Business License

DC’s Basic Business License is issued according to the activity your business conducts. A general business license isn’t interchangeable with a contractor category.

The Contractor and Construction Services page lists the supporting documents for General Contractor/Construction Manager activities, including a liability-insurance certificate, applicable occupancy and corporate records, a contract, and tax/Clean Hands records.

Applications are available through DLCP’s online system. Review current instructions and verify the correct license category before paying.

Working across borders? Holding a Maryland or Virginia contractor license does not automatically establish that you may perform licensed work in DC. DLCP says businesses conducting activity in or to the District may need a DC BBL. Its [licensing FAQ](https://dlcp.dc.gov/page/business-licensing-faqs) also states that a subcontractor doing only one DC contract still needs an applicable BBL.

5. Residential home improvement has additional requirements

Home Improvement Contractor applicants have a more extensive DLCP document checklist: liability insurance, applicable occupancy/corporate registration, a home improvement contract, a police criminal history report, a $25,000 surety bond, and tax/Clean Hands documentation.

DLCP also states that all Home Improvement Contractors and General Contractors doing residential contracting must designate and maintain a BBL for at least one Home Improvement Salesperson. This is easy to overlook if you focus only on the company’s contractor license. Salesperson licensing is a separate category with its own documents.

DLCP’s contract details page also calls for examples of pre-printed customer contracts with the application. Confirm current submission formats and contract requirements before filing.

6. Insurance, surety bonds and permits

DLCP requires Certificates of Insurance for both general contractor/construction manager and home improvement contractor licenses, and the coverage must remain current through the licensing period. Its insurance guidance spells out certificate details, insurer authorization, and other category-specific conditions.

For the Home Improvement Contractor category, DLCP specifies a $25,000 surety bond. The official bond details and DC Code §47-2883.02 explain the bond’s legal basis. A $25,000 bond is not the same as paying $25,000 in a licensing fee, nor does it substitute for liability insurance.

Clarification about evolving law: DC also enacted the General Contractor Licensing Amendment Act of 2024, addressing a residential/commercial contractor regulatory framework and financial responsibility. Its relationship to particular DLCP application categories and implementation timing should be confirmed directly with DLCP. We do not treat new statutory language as proof that every legacy license checklist has already been replaced.

Project-specific building permits and specialized trade credentials may be required in addition to your business license. Check the applicable permit authority before beginning work.

7. Know the licensing costs—and your job costs

DLCP’s Contractor and Construction Services page lists category fee schedules including $99 for a two-year license and $198 for a four-year license. A six-month option is listed for general contractor/construction manager only, not home improvement contractors. These displayed figures are not an estimate of your total startup cost: registration, bond premiums, insurance, professional qualifications, permits, and other application charges may also apply.

For job pricing, calculate your true costs: materials, labor, subcontractors, travel, permits, tools, insurance, overhead, contingencies and profit. A $5,000 invoice is revenue, not your personal income.

Build a written estimate process that you can repeat. Track what actually happened on each project so your next quote is based on experience rather than guesswork.

8. Find customers by becoming easy to trust

You don’t need to buy a large lead package before you have a reliable system. Begin with referrals, professional relationships, a clear service description, an accurate online business presence and examples of work you have permission to show.

Be responsive, put your scope in writing, confirm changes, communicate progress and leave a useful record behind. Ask satisfied clients for honest reviews. Do not advertise licenses, bonding, or insurance that you have not verified.

9. Use free tools to stay organized

Your first few jobs might be easy to remember; your first twenty won’t. Keep customer requests, estimates, appointments, project photos, documents and follow-ups in a reliable system. A spreadsheet and calendar can be enough for a small business.

For contractors participating in the Potomac Lux network, Contractor Mission Control is presented as a free contractor workspace focused on coordinating jobs and retaining useful home and project context. Confirm current feature availability during onboarding: we’re not claiming that it replaces every accounting, estimating or CRM product.

10. Official government sources and uncertainties

Use the following primary sources to check the requirements relevant to your work:

Legal source review date: October 21, 2026. DC’s newer general contractor law and the DLCP category-specific licensing instructions should be considered together. Where implementation or classification is unclear, verify with DLCP rather than treating our interpretation as official guidance. The sources don’t support promising one universal license, insurance amount, or application price for all DC contracting work.
